The World's First Immutable Record of History
A permanent archive of world events verified by decentralized consensus and stored forever on the blockchain: truth that can never be burned, rewritten, or erased.
History Has Always Been Written by Those in Power
From the burning of the Library of Alexandria to the Ministry of Truth in Orwell's 1984, those who control the past control the future. Throughout history, authoritarian regimes have burned books, erased records, and rewritten events to shape public perception and maintain power.
The Nazi book burnings. The Soviet censorship of photographs. The digital erasure of inconvenient truths. When history can be altered, truth becomes a matter of opinion.
The Library of UMA represents something unprecedented: a historical record that cannot be burned, cannot be rewritten, and cannot be controlled by any government, corporation, or individual.
Who controls the past controls the future. Who controls the present controls the past.— George Orwell, 1984
Historical Erasures
How It Works
UMA's Optimistic Oracle creates a decentralized verification system that ensures truth without central authority.
Event Submission
Real-world events are submitted to the UMA oracle with supporting evidence. Anyone can propose an event for verification.
Decentralized Verification
Token holders worldwide review and vote on the accuracy of submissions. Economic incentives ensure honest participation.
Permanent Recording
Verified events are permanently recorded on the blockchain. Once written, the record cannot be altered by anyone.
The Data Verification Mechanism (DVM)
UMA's DVM is a dispute resolution system that uses economic game theory to ensure accurate reporting. Voters stake tokens and are rewarded for voting with the majority. Bad actors who vote incorrectly lose their stake.

Why It Can't Be Corrupted
Built on blockchain technology, the Library of UMA leverages cryptographic guarantees to ensure permanence and immutability.
Immutable Records
Once an event is verified and recorded on the blockchain, it becomes cryptographically impossible to alter. No government, corporation, or individual can modify or delete the historical record.
Global Decentralization
The record is maintained by thousands of nodes worldwide. There is no central point of failure or control. The truth is protected by the collective security of the network.
Complete Transparency
Every verification, every vote, every transaction is publicly visible. Anyone can audit the process and verify the integrity of the historical record.
Eternal Permanence
Unlike physical libraries that can be destroyed, blockchain records persist as long as the network exists. The Library of UMA is designed to outlast civilizations.
